Have you ever seen currency notes so beautiful that you’d actually hesitate to spend them? Well, they’re called ‘artisanal currency’, and they’re all the rage in several parts of the world, including London, Amsterdam, and New York. The concept is quite similar to artisanal coffee, cheese, or chocolate that is handmade, not mass produced.

According to The New York Times, “these are small-batch currencies designed by locals and lovingly handled by millennials, who came of age during the rise of the Internet.” Interestingly, this local currency is not meant to be a collectible, but is legally accepted at cash-only community businesses so that the money stays within the town or district.

London’s Brixton district, for example, has its own artisanal currency designed by award-winning artist Jeremy Deller. His £5 notes feature a “fuzzy, psychedelic image of an androgynous face surrounded by rainbow clouds and swirling etchings.” Deller said that he wanted to create “something old-fashioned looking, something almost pre-currency.” And the people of Brixton are quite pleased with their own special pound notes. “I’d be more inclined to save money if it all looked like that,” said Ewan Graham, a 31-year-old architect.
